2020 Sport Climbing Olympics Tokyo
Seo qualified for the 2020 Summer Olympics in Tokyo and landed herself in the finals where she placed 8th.
This was the first installment of sport climbing at the Olympics which had a controversial format: a combination of speed climbing, bouldering, and lead climbing.
This proved difficult for Chae-Hyun who was the only finalist to have trouble breaking the 10-second barrier (which she did at the Olympics when she broke 9.85 seconds).
In the upcoming 2024 Olympics, speed climbing will be a category on its own leaving Bouldering and Lead climbing as a combined event. With this upcoming format, Seo Chae-Hyun will likely be one of the favorites to win a medal.
